摘要: 提出了一种无预刻伺服槽结构的新型可擦式磁光卡,以简单的线性移动代替传统的光盘旋转方式,其数据记录于平行于磁光卡长的一侧的信道上。磁光卡既具有磁光盘的可擦重写性能又具有光卡的便携式特点。由于离焦容差为10μm的聚焦伺服系统已在实验中建立,决定了磁光卡存储系统成本低兼并且在中等容量存储领域具有极大的市场前景。

Abstract: With no preformatted servo groove structure and simple linear moving instead of conventional disc rotation,a new erasable magneto optical card (MOC) is presented.Its data are written in tracks which are parallel to the width of the card.It possesses the advantages of MO disc erasability and optical card portability.As the defocus tolerance of ±10 μm for focus servo system is set up,the MOC storage system is low-cost and has a good potential markets in medium capacity storage fields.
